cds-question@unistra.frultraviolet-astronomyinterstellar-mediumWe present a survey of OVI {lambda}1032 emission in the Milky Way using data from the Far Ultraviolet Spectroscopic Explorer (FUSE) satellite. The observations span the period from launch in 1999 to 2003 July. Our survey contains 112 sight lines, 23 of which show measurable OVI {lambda}1032 emission. The OVI {lambda}1032 emission feature was detected at all latitudes and exhibits intensities of 1900-8600photons/s/cm^2^/sr. Combined with values from the literature, these emission measurements are consistent with the picture derived from recent OVI absorption surveys: high-latitude sight lines probe OVI-emitting gas in a clumpy, thick disk or halo, while low-latitude sight lines sample mixing layers and interfaces in the thin disk of the Galaxy.2006ApJ...647..312Ohttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/647/312CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/647/328 : FUSE survey of OVI in ISMhttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/647/312https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/647/312http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/647/312https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/647/312https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/647/312http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/647/312GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/647/312/table3 (OVI {lambda}1032{AA} 3{sigma} upper limits)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/647/312/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/647/312/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/647/312/table3?GETtext/xml+votable180.050000true269.86044-22.465740.005555555555555556Cone search capability for table J/ApJ/647/312/table2 (OVI {lambda}1032{AA} detections)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/647/312/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/647/312/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/647/312/table2?GETtext/xml+votable180.050000true308.5921825.064610.0055555555555555566/1399 1504 1805 1890 2524 2921 3053 3247 3284 5544 5564 5577 5884 5918 5966 6146 7157 7320 7980 10162 10194 10207 10695 10772 11180 11212 11242 11339 11354 11434 11643 11681 11748 11758 11984 12002 12111 12859 12983 13013 13480 13743 14197 14228 14249 14810 15351 15391 15478 15580 15842 16046 16131 18809 20423 20494 22300 23101 23540 23932 27049 28538 28915 28973 30754 31895 32781 33097 33101 33102 33115 33122 33558 33812 33888 34652 34676 36697 37140 37232 37427 37706 37819 37906 37923 38022 38110 39050 41270 41370 41763 42115 42118 42296 42324 43042 43141 43305 43874 45235 45711 45782 45909 46157 46321 46327 46646 47168 47525 48516https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/647/312?format=asciiUVdefaultJ/ApJ/647/312/table3OVI {lambda}1032{AA} 3{sigma} upper limitsrecnoRecord number assigned by the VizieR team.
